Parents who’ve diagnosed their kids with Pokmon fever have only themselves to blame, child psychologists say.

Shrinks say they’ve seen busy parents buy their children the collectible playing cards to make up for time not spent at home. Then they complain that their children eat, sleep and breath Pokmon.

Experts say the worldwide pocket-monster obsession has been fueled by moms and dads.

“I know one parent who spent a day and a half of a business trip in Hong Kong looking for a rare hologram Pokmon card for his kid,” said Jeffrey Derevensky, professor of child psychology at McGill University in Montreal. “The parent should have said no.”

Pokmon, which started out as a video game, became a multimillion-dollar playing-card craze that has morphed into widely popular daily TV cartoon and “Pokmon: The First Movie,” which is to open tomorrow.

“Children will always grab on to fads, but adults are responsible,” said child psychologist and toy expert Stephanie Pratola. “The parents are feeding this artificial economy that gets created at the expense of children.”

Although experts say the Pokmon themes of nurturing and caring for super-powered animal-like characters are in themselves benign, trading for the card can get heated.

Last month in Montreal, a 14-year old boy was stabbed over a $45 box of cards. Many New York City schools have banned the cards for fear of such violence – and to keep kids from constantly overflowing with Pokmon passion.

“We’re competing for the kids’ attention,” said Pat Sebastian, a teacher at MS 44 in Manhattan. “Even the best of kids will sneak out a Pokmon card during class.”

A Pokmon ban has been on since September at PS 87 in Manhattan, but when 3 o’clock rolls around, kids whip out binders and begin to trade.

“My parents say I’m obsessed,” said Justin Moss, a fifth-grader proud of his 150-card collection. “They tell me to put down the cards and do my homework.”

“One day, I had $60 I’d saved up from my allowance and I spent it all on Pokmon,” said fifth-grader Ian Gardner.

Parents are advised to find ways to limit their kids’ buying and trading habits.

Alpern said she’s reigned in her fourth-grade daughter, Tess. “She has to use her own money for it,” Alpern said. “I let her buy a pack once a month. And that’s it. Otherwise, it gets out of hand.”
